The vehicle is designed to combine the feel of a
motorcycle with the comfort and safety of an automobile. If
the vehicle is traveling at a constant speed of 80 km/h along
a circular curved road of radius 100 m, determine the tilt
angle 0 of the vehicle so that only a normal force from the
seat acts on the driver. Neglect the size of the driver.
A pilot weighs 150 lb and is traveling at a constant speed
of 120 ft/s. Determine the normal force he exerts on the
seat of the plane when he is upside down at A. The loop
has a radius of curvature of 400 ft.

A 0.8 Mg car travels over the hill having the shape of a parabola.
If the driver maintains a constant speed of 9 m/s, determine

that all the wheels of the car exert on the road at the instant it
reaches A.
